(February 15, 2008) MUNICH, Germany — EPP delivered several model STRATUS II AOI systems for inspection of electroplated gold, silver, and platinum. The AOI system's main application is inspection of screen-printed multilayers of ceramic thick film or LTCC substrates or LTCC foils.
The company notes that automotive electronics, high-frequency applications, and related industries increasingly are in need of electroplated gold, silver, and platinum inspection. Other suitable sectors include high-power LED circuit on ceramic manufacture, particularly in Asia. The model STRATUS II suits automatic inspection of ceramic thick-film and thin-film hybrids, LTCC/HTCC, wet adhesives, glaze print, dielectrics, and flex PCBs.
The system is available as in-line or off-line configuration and can be adapted to existing automatic production lines. It suits inspection of wet (directly after screen or stencil printing) inspection or for inspection of dry substrates (after burn in and/or after laser trimming).
The system can inspect substrates up to 12" × 12", loaded manually or automatically from magazines or cassettes. Cameras, one or two on a platform, are 4-megapixel. The machine uses linear motors for X/Y movement and a proprietary illumination subsystem. It detects screen aging, screen shift, contamination, discolouring, chip-outs in ceramic, excess print, missing print, mouse bites, bleed-outs, positioning, shift conductor/vias, etc.
Optional subsystems provide laser marker, labelling, or inking. A Verify Station to analyze defective substrates also is available.
Technical support is available in Asia, Europe, and the U.S.
